PLYMOUTH – Both sides rested on Tuesday in the trial of Christopher T. Kelly, the 40-year-old Randolph man charged with negligent driving in a dirt bike crash that killed a 14-year-old in Plymouth.

Kelly went on trial Monday in Plymouth Superior Court for the death of James Ward of Plymouth. Kelly's driver's license has been suspended or revoked 25 times.

The prosecution called police detectives who investigated the accident. One called the crash unavoidable, given the speed and path of the riders.

Defense attorney Jack Atwood called only one witness, a State Police detective who interviewed the Ward family after the accident.

On Monday, the prosecution played an emotionally charged 911 call recorded as a James Ward Sr. cradled his dying son in a Plymouth cranberry bog h on Dec. 9, 2012.

Ward visibly struggled to recount the final moments before his son’s death, frequently looking down and taking deep breaths to gather his strength. At one point, Judge Kathryn E. Hand offered a recess, but Ward declined and continued his testimony.

Ward said he and his two sons – James and younger brother Jacob – were riding dirt bikes when Kelly came around a bend and collided with James.

Jacob, now 12, could barely be seen over the witness stand as he described the fatal crash. He told of the family hobby and how the two brothers would ride with their parents. Jacob was riding an early Christmas present on the day his brother was killed. The brothers were wearing their riding gear – chest protectors, padded pants, goggles and helmets, Jacob said.

James was first in line. “He use to like being ahead of me, a lot,” said Jacob. Their father took up the rear.

As the boys came out of the woods and onto a bog, their father was about 100 feet behind, still in the woods. “I saw him (Kelly) come around the corner really wide. James tried to get away. He hit him right in the side. My brother fell, and his dirt bike continued on into the ditch,” Jacob said. “I fell off my dirt bike too. I thought he was going to come at me. I lost my balance and fell off. I ran straight over to my brother. ” Jacob described seeing a gash on his brother’s face and said, “His left boot was torn off.”

James Ward said he came around a bend and spotted Kelly on the ground, his bike running, the tires and chain still spinning, “I keep seeing that,” Ward said. “I shut Kelly’s bike off and saw James lying there.”

“I jumped off my quad. I knew it something serious. It was bad,” Ward said. Ward said Kelly told him, “I hit him pretty bad.” Ward told Kelly to get help and meet the ambulance to show the way in to the Darby Station cranberry bog.

As James Ward bent over his oldest son, he told Jacob to call 911 on his cell phone.

Assistant District Attorney Joshua W. Gedraitis presented a recording of the 911 call as evidence. A court officer had to hand out tissues to family members as they listened.

“My son’s been struck by a motorcycle. He’s not moving,” Ward says in the recording. “He hit another bike.” Ward was asked if his son was breathing, “I don’t know, he doesn’t look like he is … no … no … no.”

As Ward was instructed how to perform chest compressions he let out a cry, “Oh Jesus, no … no.”

He can be heard telling his son Jacob, “Call up Mummy, tell he what’s going on.” Amid his sobs James Ward cried, “Oh my God.”

After the fatal crash, the Registry of Motor Vehicles found Kelly was an immediate threat to the public and suspended his license for the 25th time.

According to Kelly’s driving record, his license had been suspended or revoked 24 times before the crash for a wide range of violations, including failure to stop for a pedestrian, speeding and driving on a suspended license.
